Random Values in Charts

I am having situation like I have one bundle report that include 20 sub report pages. What I want is to display is count of records associated with each report pages on the first page along with their pageexpression (table of contents style with count instead page number) and more importantly chart displaying those counts against same page expressions.

1. having prob processing count on respected pages and pull them on main page as data item.

2. chart option do take values from rmodel measures, how I am gonna route those count into chart input along with report expression as series.
